Erika Schoenberger, associate general counsel for EveryWare Global Inc. (NASDAQ:EVRY), the parent of Anchor Hocking, would not say Wednesday when the plant would reopen.

Lancaster Fire Department Capt. Brian Archer told television station WCMH that the liquid glass needs time to cool and turn solid before it can be broken for removal and the furnace fixed. Less than 10 percent of the glass in the furnace leaked.

The plant won’t open until sometime next week, reports WCMH, a news partner with Columbus Business First. There were no injuries. A similar accident occurred at the plant in January, and the cleanup cost $1.5 million, the TV station said.

The company won’t disclose how many employees are working at the plant.
